BMW has just announced that their new M8 two-door flagship sports coupe will now be available with four doors, to be named the M8 Gran Coupe and M8 Gran Coupe Competition. The new Gran Coupe will ride on a chassis and body which is 9.1-inches longer, 1.4-inches wider, 2.3-inches taller and with an increased 7.9-inch wheelbase over the M8 Coupe, which BMW notes should add improved stability, comfort and rear interior space without affecting the car’s agility on the track. Plus, BMW notes that the extra doors only add 185-pounds to the M8’s total curb weight. The M8 Gran Coupe comes with a 4.4-liter TwinPower Turbo V8 producing 600 horsepower and 553 lb.-ft. of torque, while the Gran Coupe Competition features the same engine but with 617 horsepower and 553 lb.-ft. of torque. The M8 Gran Coupe promises a 3.1 second sprint from zero to 60 mph, while the Gran Coupe Competition shaves a tenth of a second off that time, completing the run in 3.0 seconds. Top speed is limited to 155 mph, unless you opt for the M Driver’s Package, which boosts the top speed to 190 mph and also includes an invitation to the M School driver training at the BMW Performance Center in either Greer, SC or Thermal, CA. The M8 Gran Coupe will launch in the US market with a base price of $130,000 and the M8 Gran Coupe Competition will start at $143,000. Look for the vehicles to hit BMW dealers in early 2020.
